“…The results of this study demonstrate an additional conserved organizational principle between vertebrate and invertebrate brains [28], and validate theoretical considerations regarding the partitioning of valenced information to different subregions of a tiny brain [15,75]. Recently, IEG mapping has implicated nodes of the vertebrate social decision-making network (SDMN [76]) that are differentially sensitive to aggressive encounters compared to reproductive attempts in brown anoles [77], and a similar segregation of positive and negative valence was found in songbirds [32]. While no SDMN has been proposed for invertebrates, our findings point to a similar system in invertebrate brains, which awaits further elucidation.…”

“…Thus, it has been hypothesized that immediate early genes can be the molecular first responders to perceived changes in the social environment that trigger subsequent changes in the neurogenomic state of the SDMN that allows the animal to adjust its behavioral state accordingly (Cardoso et al, 2015). Several studies have documented changes in immediate early gene (IEG) expression across the SDMN associated with changes in social behavior across different vertebrate taxa (e.g., Faykoo-Martinez et al, 2018;Kabelik et al, 2018;O'Connell and Hofmann, 2012), including teleost fish and also tilapia (e.g., Field and Maruska, 2017;Roleira et al, 2017;Teles et al, 2015). In particular, changes in social status (i.e., ascending or descending in a social hierarchy) have been associated with rapid changes in IEG expression in the SDMN paralleled by changes in social behavior (Maruska et al, 2013a,b;Teles et al, 2015;Williamson et al, 2019).…”

“…We measured baseline gene expression in bold and shy individuals across six brain regions that contribute to social decision-making and are functionally conserved across vertebrates (Kabelik et al, 2018; Newman, 1999; O’Connell and Hofmann, 2011, 2012; Thompson et al, 2008; Walton et al, 2010) ( Figure 2A ; Supplemental Excel File). The number of differentially expressed genes across brain regions were relatively few (average of 8), with the exception of the ventromedial hypothalamus, where 608 genes were differentially expressed.…”

“…Among vertebrates, the lack of understanding of neuroendocrine regulators of behavioral phenotypes is especially true among non-avian reptiles, as they are the least studied vertebrate taxonomic group (Kabelik and Hofmann, 2018), despite serving as an important evolutionary comparison group, especially for amniotic vertebrates. A social decision-making network has been described in reptiles (Kabelik et al, 2018), and various neuroendocrine variables have been related to the expression of social behaviors in lizards (Dunham and Wilczynski, 2014; Hartline et al, 2017; Kabelik et al, 2013, 2008b; Kabelik and Crews, 2017; Kabelik and Magruder, 2014; Korzan et al, 2001; Korzan and Summers, 2004; Larson and Summers, 2001; Smith and Kabelik, 2017; Watt et al, 2007; Sarah C. Woolley et al, 2004; Woolley et al, 2001; Sarah C Woolley et al, 2004). However, many potential regulators of social boldness remain unexamined.…”
